Geographic referenced data (like election results). How to?

[Karlo]

Hello,

I would like to realize a 3D-chart for the following purpose:

To visualize the status of some geographic referencenced data I would like to take a map of a country as bitmap in xz direction.
In y direction I would like to position some bars.

Sample:
Visualization of election results in different citys of a country:
Percentage of Party 1: Red bar
Percentage of Party 2: Green bar
Percentage of Party 3: BlueGreen bar
A bitmap of the country should be displayed in the xz-direction.
In y direction at the geographic position of every city a bar for every of
the three partys should display the percentage of the votes.
So I would get a map with the citys on it. Every city would contain
one red, one green and one blue bar beneath.

Currently I have no idea which would be the best way to realize this.
Which series should I take? Do you have suggestions?

(I am Using TeeChart Pro 8.02 VCL, currently with D2005. As soon as possible with D2009)

best wishes

I found an image. Maybe it makes clearer what I would like to realize:
Is something like that possible with TeeChart?

I think the map series is the place to start.

I think the map series is the place to start.

The main problem: Can I position the bars in the way displayed in the graphic 2 posts before? Which series kind would be suitable for this?

The map series doesn't solve this.

Hi Karlo,

You could achieve that using Map series for the map. For each city you could use a SubChart tool, setting its walls, axes, etc. to not visible and add a cilinder bar to the SubChart tool. For positioning city SubCharts you can have a look at TeeMaps example shipped with TeeChart's installation. You could use something similar to cities callout positioning.

Hope this helps!
